In what situation would Modifier 73 be applied?

Modifier 73 is specifically used to indicate that a procedure was canceled after the patient has been prepared for surgery but before it has been initiated. This modifier is applicable in situations where the patient has undergone the necessary preoperative preparations, such as the administration of anesthesia or the establishment of an appropriate surgical environment, yet the procedure does not take place due to circumstances that arise after this preparatory phase. These could include various reasons, such as medical issues identified during the prep that need to be addressed before proceeding, or logistical issues that arise just before the start of the surgery.

In contrast, the other options do not meet the criteria for Modifier 73. For instance, elective surgery completed as planned indicates that the surgical procedure was successfully performed, thus not necessitating a cancellation modifier. Similarly, when a procedure is performed without complications, it also suggests that the surgical process proceeded as intended. Lastly, a decision made not to proceed due to patient preference would usually not involve any preoperative preparation being conducted and could require a different modifier entirely—if one at all—because the surgery was never initiated after preparation.
